Hey,
I really like your website. For the first time ever, I see the importance of the quadratic formula. However, I need some help with a step, using the triangular field to develop c = ax^2 + bx. Why is the height 2x for the two right triangles. It's probably easy, but it's a step that is mysterious to me and my long work day, tired brain.

## Very Cool Story!
